<p><b>New page</b></p><div>We use the same cold source as for [[McStas simulation projects#Simulation project: A powder diffractometer|Simulation project: A powder diffractometer]]<!--project~\ref{prob:DMC}-->. The opening we are using for the RITA-2 beam port is 0.120 m high and 0.030 m wide.<br />
<br />
The RITA-2 guide system starts 1.5 m from the source. It has a 4.5 m long straight section, followed by a 20 m curved section made from 40 0.5 m straight pieces, placed so that the radius-of-curvature is 2408 m. This eliminates the line-of-sight, so to avoid neutrons with very small wavelengths. However, in this assignment we make the simplification that the guide is straight and is in one piece.<br />
<br />
The guide material has \(m=2\) and same parameters as in [[McStas simulation projects#Simulation project: A powder diffractometer|Simulation project: A powder diffractometer]]<!--project~\ref{prob:DMC}-->. The guide has height 0.120 m and width 0.030 m along its whole length.<br />
<br />
Simulate the neutron beam intensity at the exit of the guide for neutrons in the range 0.5 Å - 20 Å.</div>ucph>Tommy
